ALBERT C. WILLIS, OF COLUMBUS, OHIO.

Specification of Letters Patent.

Patented Sept. 9, 1913.

Application filed March 7, 1913. Serial No. 752,792.

To all whom it may concern:

Be it known that I, l iLBnR'r'C. WILLIS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Churn, of which the following is a specification.

One object of this invention is to provide a churn having a novel form of gearing.

Another object ofthe invention is to improve the dasher of the churn.

It is within the scope of the invention to improve generally and to enhance the utility of,"devioes of that type to which the present invention appertalns.

With the above and other objects in view,

which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood .that

changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit ofthe invention.

In the drawings Figure 1 shows the invention in end elevation; Fig. 2 is a side elevation; Fig.3 is a vertical transverse section of the dasher; Fig. 4 is a side elevation of the dasher; and Fig. 5 is a longitudinal sectionaldetail showing a modified form of dasher.

In carrying out the invention there is provided a frame denoted generally by the numeral 1, the frame comprising spaced base strips 2, supporting converging uprights 3, the upper ends of which are united by a top plate 4. The uprights 3 are spaced inwardly, as indicated at 5, from the outer ends of the base strips 3, and cleats 6 are .secured in the angles defined by the uprights 3 and the base strips 2. Mounted upon the top plate 4 is a base plate 7 held in place by means of bolts 8, the base plate 7 being provided with a depending arm 9 which eX- tends downwardly along the uprights 3 at one end of the frame v1, the lower end portion of the arm 9 being secured by means of bolts 10 to the uprights 3. Formed integrally with the base plate 7 located in alinement with the arm 9 is a standard 11. v

Another standard 12 is formed integrally with the base plate 7, the standards 11 and 12 being connected by a web 14 which is formed integrally with the base plate 7. Located at the upper end of the standard 12 is a bearing 15. Another bearing 16 is located at the upper-send of the standard 11, the bearing 16 being formed integrally with the standard 11. and with a flange 17 whichprojects laterally from the arm 9.

A shaft 18 is journaled for rotation in the bearings 15 and 16 and at its outer end is provided with a pinion 19 meshinginto the diate its ends, the crank 25is formed with an enlarged boss 27, receiving a screw 28, whereby the crank 25 is connected with one of the spokes of the gear wheel 20. Formed integrally with the base plate 7 and upstanding .from one end of the base plate is a bearing 29 in which is journaled' forrotati-on a shaft 30. A collar 31 surrounds the shaft 30 and rests upon the upper end of the bearing 29. The collar 31 is provided with a ball race receiving balls 32, the balls 32 cooperating with -a ball race formed in the hub 33 of .a beveled pinion 34, the hub 33 of the beveled pinion 34 being secured to the shaft 30 through the medium of a set screw 35. The beveled pinion -34 meshes into a beveled pinion 36 having a hub 37 which is secured to one end of the shaft 18. The lower end of the shaft 30 extends through the top plate 4 of the frame 1 and is received within the upper end of the bushing 40 mounted in the hub 38 of a fly wheel 39, thefly wheel 39 being disposed below the top plate 4 of the frame 1. A set screw 41 enters the hub 38 and serves to connect the bushing 40 and the hub 38 for simultaneous rotation, the set screw 41 engaging, also, the shaft 30, in order to hold the fly wheel 39 and the shaft together for simultaneous rotation. The lower end of the bushing 40 receives the upper end of a da'sher'shaft 42, the dasher shaft 42 being provided adjacent its upper end with a transverse pin 43, the ends of which are received in a transverse groove 44, formed in the lower end of the bushing 40. The lower end of the dasher shaft 42 is received in a thrust bearing '45 supported 51 and 52 are provided with openings 53,,

upon the bottom of a receptacle 46, the receptacle 46 resting removably upon the base strips 2 of the frame 1. The receptacle 46 is provided with a lid 47 having an opening 48 receiving the dasher shaft 42. The receptacle 46 is provided in its interior with oppositely disposed, inwardly projecting vanes 49, the upper and lower edges of which are spaced, respectively, from the lid 47 and from the bottom of the receptacle.

The dasher employed in the churn forming the subject matter of this application, is shown in detail in Figs. 3 and 4. Referring to these figures, the dasher comprises side plates 50 connected by converging end plates 51. Located between the end plates 51 and terminally mounted in the side plates 50 are intermediate plates 52. The intermediate plates 52 diverge toward the converging ends of the end plates 51. All of the plates the openings 53 being disposed in lines which converge upwardly. A supporting block 54 of approximately triangular cross section is secured to the uppermost end plate 51, and located on top of the block 54 is a cap 55 provided with depending flanges 56 engaging the front and rear edges of the block 54. The cap 55 is provided with a bearing 57. Through the bearing 57 through the block 54 and through the plates 51 and 52 passes the dasher shaft 42, the dasher Y shaft being held in place in the bearing 57 by means of a pin 58.

In Fig. 5 of the drawings, a slightly modified form of the: invention is shown, so far as the dasher is concerned. The dasher shown in Fig. 5 comprises side plates 59 and transverse plates 60, the plates 60 being provided with the openings'53 hereinbefore described. Located on top of the uppermost plate 60 is a block 61 supporting a cap 62 provided with depending flanges 63, the cap 62 being equipped with a bearing 64, receiving the dasher shaft, the dasher shaft being held in the bearing 64 by means of a pin 65.

Uwing to the fact that the lever 25 is provided withthe eye 23 which receives the hub 22 of the gear wheel 20, the gear wheel and the crank may be removed from the shaft 21, without separating the gear Wheel and the crank. I

It is to be observed that the fly wheel 39 is located below the top plate 4 of the frame and relatively near to the dasher. Owing to this construction, the torsion imposed on the shaft 42 is reduced to a minimum, and the effect of the fly wheel 39 is applied to the shaft 42 as close as possible to the dasher. Owing to the fact that the upper end of the shaft 42 is engaged in the bushing 40, the bushing 40 being surrounded by the hub 38 of the fly wheel 39, an unusually strong union between the shaft 42 and the fly wheel 39 is effected.

The dasher hereinbefore described and shown specifically in Figs. 3 and 4, as well as the dasher shown in Fig. 5, is of peculiar efliciency in securing a thorough agitation of the contents of the receptacle 46. Owing to the fact that the intermediate plates 52 di verge in the direction of convergence of the plates 51, the cream or other material is given a vertical, reciprocating motion. Further, the cream, as it passes through the openings 53, will be drawn toward the longitudinal center of the receptacle 46, and thus, the agitation of the contents of the receptacle is promoted.

- Having thus described the invention, what is claimed is 1. A churn dasher comprising side plates; converging end plates located between the side plates and disposed transversely of the side plates; intermediate plates located between the side plates and disposed transversely of the side plates, the intermediate plates diverging in the direction of convergence of the end plates; a shaft extended through all of the plates; the plates being provided with two lines of openings the lines of openings being located upon opposite sides of the shaft, the lines converging toward the top of the dasher.

2. A dasher having a fixed axis of rotation and comprising a plurality of plates disposed at right angles to the axis of rotation and in vertically alined horizontally zig-zagged relation, the plates being provided with openings disposed in lines converged toward the top of the dasher.

3. A dasher comprising a shaft; and plates disposed transversely of the shaft; the plates being provided with two lines only of openings, the lines lying on opposite sides of the shaft and converging toward one end of the shaft.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
